Abstract: 1,087,692. Electric selectors. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Sept. 3, 1964 [Sept. 4, 1963], No. 34888/63. Heading H1L. An electric selector wiper assembly includes a unitary plastics moulding, preferably of polyacetyl resin, comprising a plate 10, on opposite faces of which wipers 17, 18 are mounted, and an upstanding collar portion 11 for clamping to a tubular carriage (not shown) by a strap 31 and screw 32; one end of the strap being slotted to release one end of the screw. The wipers 17, 18 are held to the plate by screws 26, 27 which enter untapped plastics bushes passing through the plate from the opposite side: the bushes are linked on this opposite side by a cross-piece with which they form another single plastics moulding. Washers 29 of insulating material are provided. The wipers 17, 18 may be biased away from one another, instead of together as shown, in which case the tongue 14 of the plate 10 has a restricted portion for flexibility.

Abstract: 397,737. Moulding clay thimbles for holding pottery in kilns. AYNSLEY, H. M., (trading as TAYLOR & CO.), Church Street, Longton, and SHUFFLEBOTHAM, H., 15, Newport Street, Burslem, both in Staffordshire. Dec. 10, 1932, No. 35034. [Class 87 (ii).] Clay thimbles for holding pottery in kilns are made by feeding roughlyshaped pieces of clay alternately to two intercoupled pressing elements located side by side with one set forward of the other, each piece of clay being subjected to a double pressing by the particular pressing element to which it has been fed, after which it is removed and a fresh piece placed in position for pressing, the change being effected in each pressing element during the double pressure operation in the other pressing element. A press. may be employed having two separate pressing elements incorporated therein or two individual presses may be coupled together for example as shown in the drawing. The apparatus shown comprises a frame 1 carrying vertically sliding members 2, 11, the member 11 being set forward of the member 2, at the lower end of each of which is an upper die, not shown, registering with a bottom die also not shown. The member 2 is driven by a crank and connecting rod 3 from a gear wheel 4 on a driven shaft 5. The member 11 is driven by a crank and connecting rod 10 from a gear wheel 9 on a shaft 8 on which is mounted another gear wheel engaging the wheel 4.. As shown when one press is at the bottom of its pressure stroke the second one is nearly at the top, this setting may however be varied if desired.

Title: Improvements in and relating to starters for electric motors
IPC: H02P1/20
Filed: 1922-12-27
Abstract: 209,287. Igranic Electric Co., Ltd., and Pickering, G. H. Dec. 27, 1922. Controllers with multiple rocking bars. - In starters such as are employed for printing press motors, a set of armature resistance contacts and a set of field resistance contacts are carried on a single movable structure so as to co-operate in succession with a like number of stationary contacts, whereby the armature resistance is first progressively reduced and afterwards the field resistance is increased. In the apparatus shown in the drawings the armature resistance contacts 5 are spring-mounted upon an elongated plate 9 which can be rocked upon an axis XX by a retarded solenoid 7. The field resistance contacts 6 are mounted upon a bar 12 attached to the plate 9 and parallel to its axis. During the first part of the up-stroke of the solenoid core, the armature contacts in succession are pushed up to corresponding stationary contacts 5a, whereby starting resistance is short circuited. During the remainder of the stroke, the field contact fingers 6, which initially rested upon corresponding stationary contacts, are pushed away from them in succession by encountering stationary posts 16, whereby resistance is inserted in the field circuit. The solenoid is controlled by a push-button so as to proceed to the end of its stroke automatically after a momentary closure of the button. An alternative button is provided for inching.

Filed: 1977-08-24
Abstract: 1532349 Etching holes through dielectric material INTERNATIONAL BUSINESS MACHINES CORP 24 Aug 1977 [28 Oct 1976] 35554/77 Heading B6J [Also in Division H1] A hole is formed through dielectric material, e.g. glass, SiO 2  or Si 3 N 4 , covering a raised conductive strip pattern disposed on a substrate. The dielectric material is deposited over said pattern and said substrate so that the topology of said dielectric material includes protuberances conforming to said pattern. Next a second material is deposited over said dielectric material filling the regions between said protuberances to a greater thickness than that over said protuberances. A photoresist masking layer is then formed on said second material having an opening over a selected protuberance, thereby exposing a portion of said second material which exposed portion is then removed, e.g. by sputter etching. The dielectric material is then etched through the opening in the second material to form a hole in the dielectric material to expose a region of the pattern. The second material may be a photoresist which is baked after deposition to render it insensitive to exposure.

Abstract: 1516256 Automatic microphone mixer; gain control D W DUGAN 26 Aug 1976 35557/76 Heading H4J A signal control system for a plurality of input signal channels comprises, for each channel controlling means for multiplying the input signal by the quotient of the average input signal divided by the average of the sum of all the input signals, so that the total gain of the system remains constant. In the embodiment a summing amplifier 9, log envelope detector 10 and inverter 10a, common to all the channels 1-N, are used to obtain the log of the average of the sum of all the inputs through resistors 4,4<SP>1</SP>. In each channel e.g. 16 a log envelope detector 5 provides the log of the average of the input to this channel. A summing amplifier 6 adds the outputs of detector 5 and inverter 10a and its output controls the attenuation of attenuator 7, which is a voltage controlled amplifier, employing LED and photosensitive resistors, with an antilog characteristic, in accordance with the ratio of the input signal to the sum of all the input signals. The system is used in a sound reinforcement system, in which each channel includes a microphone e.g. 1, 1<SP>1</SP> and the outputs of all channels and combined by a summing amplifier 11 and fed to a loudspeaker 15. Figs. 2 and 3 (not shown) disclose details of the envelope detectors (5, 5', 10) summing amplifiers (6, 6') and attenuators (7, 7').

[Class 130] [See also Group I] An apparatus for treating tobacco leaves comprises a mechanism U for removing stems from a succession of tobacco leaves and means for conveying the stemmed leaves directly to a mechanism 32 for cutting the leaves into shreds suitable for cigarette tobacco. A conditioning chamber 26 may be interposed between the stemming and shredding mechanisms and the latter may deliver the tobacco through drying and cooling chambers. As shown in the Figure, the stemming mechanism U comprises feed belts 1<a> by which the leaves are fed over a table 1 into position to be engaged by grippers on a travelling chain, which carry the leaves through narrow suction chambers 4 in order to spread, straighten and clean them. The leaves are conveyed by suction means to stemming mechanism of a type arranged to tear the stems lengthwise from the leaf webs, preferably from the tips towards the butts. The stemmed leaves are transferred to a collecting belt 52 by means of a suction belt 53 from which the suction is periodically cut off, and the belt 52 carries the leaves in flat outspread condition through the conditioning chamber 26 to the shredding mechanism 32. In modifications, a number of stemming mechanisms are arranged to deliver stemmed leaves to a single collecting belt corresponding to the belt 52. These modifications, and the construction and arrangement of the shredding mechanism and the subsequent conditioning means, are described in Specification 455,098.
